Installation
Select a clean, dry location with good ventilation and
adequate working space around all components.
All gas inputs and two control cables attach to the rear
panel. A fiber-optic control cable passes through the
rear panel and connects to a printed circuit board in-
side the module. There must be adequate space be-
hind the module for these hose and cable connections
without crimping.
The Gas Control Module must be installed in a suitable
location where it is easily accessible to the system op-
erator. The unit must be mounted to a flat horizontal
surface. If the module is mounted to a gantry or any
other support subject to vibration or motion, the in-
staller must fasten the module to the support securely.
The module should be located as far away as possible
from the Arc Starter due to electromagnetic interfer-
ence. It is acceptable to locate the control cable in the
same track as the cables from the Arc Starter.
The module includes feet which lift the bottom panel
off the mounting surface. There are ventilation holes
on the bottom panel; the space between the bottom
panel and the mounting surface must remain open for
ventilating air to enter the module. Louvers on the back
panel of the module must also remain unblocked, for
the free passage of ventilating air.
NOTE
The unit must be mounted so that the Flowmeters
are plumb. If the Flowmeters are not plumb,
incorrect flow indications may occur.
